Hello
Most of my seedlings are doing fine. Sown on the 23rd Feb. Some are now in the Greenhouse, but there is an unusual marking on the 2 leaves of one plant which has alwasy been indoors, mainly under growlights (amateur variety, new seeds) - photo below. Is this something to be concerned with, have I over \ under watered, is it a disease?
The plant itself is coming on ok sizewise
edit - I should as the leaf is not quite as yellow as it looks in the first photo with the flash, but it is lighter than some others.
Thanks
Al
